Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has bactericidal activity against a broad range of gram-positive and gram-negative bacteria.
Cephapirin sodium is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP1 and PBP3, thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes.
1-2 g intravenously or intramuscularly every 24 hours. Maximum dose: 4 g daily.
500 mg to 1 g IM or IV every 6 hours.

Terminal elimination half-life is approximately 5.8-8.7 hours in adults, prolonged to 12-24 hours in elderly, and up to 30-72 hours in neonates. No dose adjustment in renal impairment alone; adjust in severe hepatic impairment.
0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Renal (33-67% unchanged) and biliary (up to 40% as unchanged drug and microbiologically inactive metabolites); fecal elimination of unabsorbed drug is minimal. Dose adjustment required in combined renal and hepatic impairment.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
